A4 figure ready to print

How can I create a GUI, or I should say a figure that has the same proportion of a A4 sheet, so that I can put in this figure all the edit-boxs and static-boxs that I need... and at the end print the entire page in A4 format, without changing the proportion (Fill Page in Print-preview).

Thanks

Using the papersize property of your figure shoud achieve what you you wish: Changing a Figure's Settings

If I want to display the A4 sheet/GUI on the screen, the dimension of the gui height must be the height of the screen.

For example: if I have a screen [1024 x 769] pixel

The A4 GUI must be [.... x 769] I don't know which relation might be between cm and pixel....
